S275JR steel pipes are widely used in various industries due to their excellent mechanical properties and versatility. This article provides a detailed overview of S275JR pipe dimensions, including outer diameter, wall thickness, yield strength, and tensile strength. Typically, these pipes range from 10 mm to 500 mm in outer diameter and can have wall thicknesses tailored to specific applications.When searching for S275JR pipes for sale, it’s essential to evaluate suppliers based on their quality standards, certifications, and customer reviews.
Outer Diameter Range: 21.3 to 610mm
S275JR pipes are available in a wide range of outer diameters to suit different applications. The outer diameter of S275JR pipes typically ranges from 21.3mm to 610mm. This extensive range allows for flexibility in design and installation across various industries, including construction, oil and gas, and manufacturing.
The most common outer diameters for S275JR pipes include 21.3mm, 26.9mm, 33.7mm, 42.4mm, 48.3mm, 60.3mm, 76.1mm, 88.9mm, 114.3mm, 139.7mm, 168.3mm, 219.1mm, 273mm, 323.9mm, 355.6mm, 406.4mm, 457mm, 508mm, and 610mm. These standardized sizes ensure compatibility with fittings and accessories across different manufacturers and projects.
It's important to note that while the range extends up to 610mm, larger diameters may be less readily available and might require custom ordering or longer lead times. Always consult with your supplier to confirm the availability of specific sizes for your project needs.
Wall Thickness Range: 2mm to 100mm
The wall thickness of S275JR pipes is another crucial dimension that affects their performance and suitability for different applications. The wall thickness range for S275JR steel pipe typically spans from 2mm to 100mm, offering a broad spectrum of options to meet various strength and weight requirements.
Thinner wall thicknesses, such as 2mm to 10mm, are commonly used in applications where weight is a concern or where the pipe is not subjected to high pressures. These thinner-walled pipes are often employed in structural applications, light-duty pipelines, and general-purpose use.
Medium wall thicknesses, ranging from 10mm to 30mm, strike a balance between strength and weight. They are suitable for moderate pressure applications and are frequently used in the construction industry, process piping, and general engineering purposes.
Thicker wall options, from 30mm up to 100mm, are designed for heavy-duty applications where high pressure resistance and structural integrity are paramount. These pipes are often used in high-pressure systems, offshore platforms, and critical load-bearing structures.
It's important to select the appropriate wall thickness based on the specific requirements of your project, considering factors such as internal pressure, external loads, and environmental conditions. Always consult engineering standards and specifications when determining the suitable wall thickness for your application.
Yield Strength
The yield strength of S275JR steel pipe is a critical property that determines its ability to withstand stress without permanent deformation. For S275JR steel, the minimum yield strength varies depending on the thickness of the material:
- For nominal thicknesses ≤ 16mm: The minimum yield strength is 275 MPa.
- For nominal thicknesses > 16mm but ≤ 40mm: The minimum yield strength is 265 MPa.
- For nominal thicknesses > 40mm but ≤ 63mm: The minimum yield strength is 255 MPa.
This variation in yield strength across different thicknesses is due to the metallurgical properties of the steel and the manufacturing process. Thicker sections tend to have slightly lower yield strengths due to slower cooling rates during production, which can affect the microstructure of the steel.
The high yield strength of S275JR pipes makes them suitable for a wide range of applications where resistance to deformation under load is crucial. This property ensures that the pipes maintain their shape and structural integrity under normal operating conditions, contributing to the overall safety and reliability of the systems in which they are used.
Tensile Strength: 410-560 MPa
The tensile strength of S275JR pipes ranges from 410 to 560 MPa. This property indicates the maximum stress that the material can withstand before failing under tension. The wide range of tensile strength values allows for some flexibility in material selection based on specific project requirements.
The high tensile strength of S275JR pipes contributes to their durability and reliability in various applications. This property is particularly important in situations where the pipes may be subjected to tensile loads, such as in suspended piping systems or structures exposed to wind or seismic forces.
It's worth noting that the actual tensile strength of a specific S275JR pipe may fall anywhere within the 410-560 MPa range. Manufacturers typically provide more precise tensile strength values for their products based on testing results. When selecting S275JR steel pipe for critical applications, it's advisable to consult with the manufacturer or supplier to obtain specific strength data for the pipes you intend to use.
